Specification of Letters Patent.

Patented June 9, 1914.

To all whom it may concern:

Be it known that I, FRANK O. HOAGLAND, a citizen of the United States, residing at Bridgeport, county of Fairfield, vState of Connecticut, have invented an Improvement in Illuminating-Bullets, of which the following is a specification. Y

This invention has for its object to provide an inexpensive bullet adapted more especially for target shooting and for range finding, which shall resemble an ordinary lead bullet and be adapted to be handled freely and which upon impact will produce a flash of light or a puff of smoke, or both, which will show if it strikes a target, and where, and in other uses will show where the bullet strikes relatively to the mark and if the gun sights require adjustment for distance. With these and other objects in view I have devised the novel illuminating bullet which I will now describe, Areferring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts.

Figure 1 is a sectional view illustrating-'a form of slug for my novel bullet; Fig. 2 a plan of the slug, that is as seen from above in Fig. 1; Fig. 3 a sectional view corresponding with Fig. 1, illustrating the completed bullet; Fig. 4 an elevation o f another form of slug for my novel bullet, and Fig. 5 is a view partly in elevation and partly in section of the completed bullet, corresponding with Fig. 4. p Y

The essential feature of the invention is that the slug is formed with an annular groove, having an overhanging wall on one or both sides, comprising a recess adapted to receive a mass of any suitable-flashing compound, indicated by 10, which is retained in the recess by closing the wallV or walls down upon it and when ignited by the impact of the bullet will burst its way out of the recess and produce a flame of any desired color, or a puttl ofsmoke, or both.

In the form illustrated in Figs. 1, 2 and 3,

sides and the forward end thereof as provided with a backwardly extending annular groove 11. The inner wall of the groove is shown as parallel with the axis of the slug, leaving the central portion 12 of the Vslug projecting beyond the outer wall 13. It will of course be understood `however that the special details of construction, as the special shape of either groove, central portion or outer wall, or the depth of the groove are wholly immaterial so far as the principle of the invention is concerned. rlhe flashing compound is placed' in the bottom of the groove and then the forward end of the slug is subjected'to a swaging action which imparts to the completed bullet the desired configuration and closes the outer wall inward upon the cent-ral portion, thus tightly inclosing the flashing compounds in a recess indicated by 17 and leaving it protected by the metallic wall or walls. The swaging action also closes the edge at the outer end of the central portion over upon the end of the outer wall, kas shown in Fig. 3, leaving the flashing compound protected by the wall or walls. The recess is made air andwater tight and oil and grease proof by the closing together of the end of the outer wall and the edge of the central portion, as at 14.

The form illustrated in Figs. 4 and 5 differs in that the groove 15 is formed at right angles to the axis of the bullet instead o-f parallel with the axis, as in the other form, and a wall 16 is formed upon each side of the groove. placed in the groove asbefore and then the walls are swaged down upon it leaving the flashing compound confined and protected in an air, water and oil tight annular recess as before. i

The operation upon impact will be obvious.v The flashing compound in the recess is ignited and bursts vits way out, indicating by means of a flash or a puff of smoke, or both, the point of impact of the bullet.

' Having thus described my invention I claim:

1. An illuminating bullet having a recess formed therein, said recess lying. between an. outer wall and a solid cylindrical portion, a liashing compound in said recess secured therein, and the recess made air, water and oil tight by the closing in of the wall upon the solid cylindrical portion.

2. An illuminating bullet having an annular groove formed therein, a flashing compound in the groove and a metallic protection for the compound formed by closing the wall over the groove.

3. An illuminating bullet comprisin av slug having an annular recess exten ing The flashing compound is formed by swaging the outer wall inward backward from its forward end, leaving a solid central point portion and an outer wall7 a ashing compound in the groove and a, metallic protection for said compound FRANK O. HOAGLAND.

and the edge of the central portion over upon the end of the outer wall.
